OIL-BURNER.

Application filed March 27, 1914.

To all 'whom it may concern.'

Be it known that we, SID PERRY and CHARLES A. KnNwoRTHY, citizens of the United States, residing at Tenino, in the county of Thurston and State of Washington, have invented certain new and useful' Improvements in Oil-Burners, of which the following is a specication.

This invention relates to improvements in oil burners, and one of the objects of the same is to provide an improved burner of this character having means whereby any foreign matter in the nozzle may be readily and quickly cleaned or blown out, necessitating only a very short interval of time for such cleaning operation, and without dismantling or removing the burner, or any part thereof.

A further object is to provide an improved burner of this character having means whereby all fuel may be blown out or cleaned therefrom when shutting down, thereby preventing any drip or the formation of gas, when the burner is not in use.

To the attainment of these ends, and the accomplishment of other new and useful objects as will appear, the invention consists in the features of novelty in substantially the construction, combination and arrangement of the several parts hereinafter more fully described and claimed, and shown in the accompanying drawing, in which- Figure 1 is ay vertical longitudinal sectional view of an improved burner of this character constructed in accordance with the principles of this invention. Fig. 2 is a detail sectional view on line 2-2, Fig. 1. Fig. 3 is a detail sectional view on line 3 3, Fig. 1.

Referring more particularly to the drawing and in the present form of this invention, the numeral 10 designates an oil chamber preferably in the form of a tube, and into which the oil is fed through a supply pipe 11, which is connected by means of a coupling 12 to a line pipe 13, and a controlling valve 14 is provided for regulating the supply 'of oil into the chamber 10. This chamber 10 is provided with an open forward end 15 having threads 16 around the periphery thereof, and on to which threaded end a tapering nozzle 17 is removably secured, so that the nozzle may be readily removed in the event that it becomes burnt or otherwise damaged. This chamber 10 is Specification of Letters Patent.

supported preferably by being screwed on to the end'of the pipe 11 as at 18, and also by means of a branch pipe 19 which has communication with the chamber 10, and which pipe 19 leads from a steam or air line pipe 20. Arranged within the chamber 10 is a pipe 21, which is of a diameter considerably smaller than the diameter of the chamber and this pipe is of a length to extend through a stuffing box 22, which latter formsl a closure for the other end of the chamber 10. The pipe 21 is held against rotation with respect to the chamber 10, but for longitudinal adjustment with respect thereto, by means of a set screw 10 entering the groove 21.

The pipe 21 is provided with an open extremity 23 having threads 24 around the periphery thereof, and a tapering nozzle 25 is removably secured to the threaded extremity of the pipe 21. The nozzle 25 is also of a size somewhat smaller than the nozzle 17 and is so arranged that it will discharge centrally through the nozzle 17. The pipe 21 is of a length to extend for some distance beyond the stuffing box 22 and this portion ofthe pipe is provided with peripheral threads 26. A stuing box and nut 27 is provided which threads on to the extremity of the threaded portion 26 of the pipe 21 to form a closure for this pipe, and a pipe 28 connected with the pipe 2O by means of a coupling or joint 29 is provided and the extremity of this pipe 28 projects through the stuffing box and nut 27 to discharge into the'interior of the pipe 21, and this pipe 28 is of such len th that the pipe 21 may be movedlongitu inally with respect to the chamber 10 andthe pipe 28, so as to adjust the nozzle 25 with respect to the nozzle 17. M

' to the pipe 21, through the pipe' 28, and a valve 31 is provided' in the branch opening and closing the same.

It will thus be manifest with this improved construction, the pipe 21 may be pipe for `moved longitudinally with respect to the chamber 10 to vary the position of the nozzle 25 with respect to the nozzle 17, so

ioo

that should any foreign matter become lodged within the chamber 10, the pipe 21 may be moved backwardly so that the discharge end of the nozzle 25 may be positioned to the rear of the foreign matter and then th-e steam pressure through the nozzle 25 will blow the foreign matter out of the chamber 10 and nozzle 17, through the discharge end of the latter. rIhe supply of oil is controlled by means of the valve 14 so that the oil will be discharged into the chamber 10, and then the valve 30 is opened to admit steam into the pipe 21, and the passage of this steam through the pipe 21 and out of the nozzle 25 will cause the oil in the chamber 10 to be atomized through the nozzle 17 the amount of oil and steam being controlled by the respective valves. lt will also be manifestthat the nozzle is removably supported by the coupling 12 and the coupling 32.

The pipe 21 may be adjusted with respect to the chamber 10 in any desired or suitable manner, but in the present exemplilication of this invention, the threaded portion 26 thereof is provided for this purpose, and cooperating with this threaded portion 26 is a sleeve or collar 33 which is threaded thereon. Connected with the sleeve is a handle 34, preferably of a substantially U shape formation, with one leg 35 thereof entering a soclret in the sleeve 33, and being held against displacement by means of a suitable set screw 36. rfhe other leg 37 of the handle is preferably shorter than the leg 35 and the extremity of this leg 37 projects into a groove 38 provided around the chamber 10, and the set screw 36 serves also as a means for holding the extremity of the leg 37 seated in the groove 38. A hand hold 39 may also be provided on the handle 34. Thus when it is desired to adjust the pipe 21, and the nozzle 25 with respect to the nozzle 17, all that is necessary is to grasp the hand hold 39 and rotate the handle 34, to cause the end of the leg 37 to traverse the groove 38 and to be rotated about the chamber 10. This will cause the sleeve or collar 33 to be rotated and during such rotation, the sleeve having` a threaded engagement with the threaded portion 26 of the pipe 21, will cause the pipe 21 of the nozzle 25 to be moved longitudinally with respect to the chamber 10 and the pipe 28, in one direction or the other according to the direction of rotation of the handle 34, and so as to position the nozzle 25 at any desired point in the chamber 10 or in the nozzle 17, so as to blow out any foreign matter Without shutting down or stopping the apparatus with which the nozzle is employed.

`When it is desired to discontinue the use of the burner, and in order to prevent any oil from remaining in the chamber 10, which would cause a. dripping or the formation of gas when the nozzle is not in use, a bypass or branch pipe 19 is provided, and is adapted to be opened by means of the valve 31, and when the oil valve 11iis closed, it permits the steam to flow through the bypass and into the chamber 10 to a point adjacent its rear end, to blow out any oil therein.

lVith this improved construction it will be manifest that the burner is connected to the pipe lines in such a manner that it may be easily removed without disturbing the pipe lines and it will also be manifest that there is provided a burner of an extremely simple construction and positive operation, and one which may be cheaply manufactured and installed. Provision is also made that when any part becomes damaged, it may be quickly replacedwith very little loss of time.

llVhile the preferred form of the invention has been herein shown and described, it is to be understood that various changes may be made in the details of construction, and in the combination and arrangement of the several parts, Within the scope of the claims, without departing from the spirit of this invention.
